MLT ASCP PRACTICE EXAM SCRIPT 2026
COMPLETE QUESTIONS AND ANSWERS
◉ What are the 2 T cell co-receptors? Answer: CD4 and CD8
◉ What are the T cells surface rceptors. Answer: TCR 1 and TCR 2
◉ Which T cell receptor becomes memory cells and release cytokines?
Answer: CD4
◉ Radial Immunodiffusion (RID). Answer: An immunoassay based on
the direct observation of antigen-antibody reaction within a gel matrix
◉ Radial Immunodiffusion tests for. Answer: Antigen concentration via
precipitatin zones
◉ precipitation reaction. Answer: Detects immune lattice complex
formation: Ag-Ab forms
◉ precipitation reaction. Answer: Ag-Ab lattice forms and diffuses out
of solution, visibly seen as becoming insoluble
,◉ Prozone precipitation. Answer: Antibody excess
◉ Postzone in precipitin curve. Answer: Antigen excess
◉ What is the optimal precipitation zone. Answer: When Antigen-
Antibody are at equal levels
◉ What could cause toe or more precipitatin bands to form in an
Antigen-Antibody experiment? Answer: The antigens are different from
each other and this the precipitation bands will be different and cross-
react
◉ The following dilutions were set up to utter an antibody. The
following results were obtained: 1:4+, 1:8+, 1:16+, 1:32+, 1:64-. How
should the tiger be reported out? Answer: 32
◉ The RPR is a test for which STD? Answer: Syphilis
◉ is the RPR test for treponema's or nontreponemal? Answer:
Nkntreponemal
◉ What is a confirmatory test for syphilis? Answer: FTA-ABS
, ◉ After infection, a patient develops Reagin antibodies of the
nontreponemL type for this STD? Answer: Syphilis
◉ A new lab assay gave the following results: number of patients
tested= 100; number of true positives= 54, number of true negatives=
42; number of false positives= 2; number of false negatives=2. What is
the specificity ? Answer: 95.45%
◉ What immunoglobulin crosses the placenta? Answer: IgG
◉ ANA pattern: homogenous/diffuse associated with what AID?
Answer: SLE
◉ AIDS confirmatory test. Answer: Western blot method
◉ Largest immunoglobulin. Answer: IgM
◉ Immunoglobulin with highest concentration in serum. Answer: IgG
◉ The only immunoglobulin that fixes complent. Answer: IgM
◉ Dimeric immunoglobulin. Answer: IgA
